Propane troubles
 
Having troubles with the propane systems on our 2017 21QB. The stovetop burners work fine, but that's all. No water heater, no furnace, no fridge. The fridge works perfectly when we're plugged in. Any thoughts what the problem might be? Do you think it's fixable by someone who's not very handy? (We're on a trip and would rather not have it sitting at a repair shop while we twiddle our thumbs). Thx. p.s. we were at 7000' for a while, but now back at sea level.

Have your checked your 12v system and voltage? The water heater, furnace, and fridge all use 12v for propane control and ignition but the stove does not.

Technically illiterate newbie... How do I check 12V system? p.s. the lights work fine on battery.

Are you sure your stove is working properly or just barely burning? There is a safety device built in the propane system that prevents rapid dischage of propane. If you open the valves quickly the out rush of gas into your piping can trigger the safety device. I would recommend, closing the valves on the tanks, waiting about 5 minutes, then slowly reopen one valve at a time. Light the stove and let it burn for a minute or so. Then try your other appliances one a a time.

Is your stove the farthest gas user from your tanks? If not you may need to bleed the air out of the line at the farthest point from the tanks by operating that appliance through its start cycle several times.

I'm familiar with your TT, as we own the predecessor model. The water heater is closest, the stove and fridge are across from each other, and the furnace is in the back corner under the sofa. If the stove burns properly propane has gone farther down the pipe past the water heater. Is this the very first time you've used any of these appliances?

We've used them all multiple times. The 12v issue seems likeliest. How do we test for that? Would that be it if the lights are working when on battery? Thx.

Give me a minute to go out to our TT and get my wiring schematic, They should be close to the same. Be right back.

On the 12 volt side of the electric, the fridge and furnace are fed from the same fuse. The water heater is only gas, or 120 volt.

On the 120 volt side, the fridge, and bathroom GFCI, outlet to the left of the sink, and (on ours) the front outside 120 volt outlet are on the same circuit breaker. The water heater has it's own breaker.

If you're getting gas to the stove, it should be getting to the water heater and fridge. Sometimes they have to cycle two or three times, till they catch. Burning the stove does help.

The best way to check the battery is with a voltmeter. About 12.55 or better is good.

Thx much for all your help!
